## Vinyl tiles

Unlike rolls of flooring which are sold in lineal metres, tiles are priced by the box and charged either as a piece count or coverage in square metres.

When it comes to calculating the quantity of tiles needed for an installation job, it's safest to use the piece count because that lets you account for the individual tiles that will need trimming.

**Step 1: Divide the width of the area by the tile width**

2630 (width of room) ÷ 300 (width of tile) = 8.7, so 9 tiles will be needed.

**Step 2: Divide the length of the area by the tile width**

3540 (length of room) ÷ 300 (width of tile) = 11.8, so 12 tiles will be needed.

**Step 3: Multiply the width and length quantities**

9 x 12 = 108 tiles.

### Balancing border tiles

There are times when it's best to balance the width of the border tiles, particularly when you can see both sides of the floor area at once.

This means that instead of trimming the border tiles on one side only, you halve the finished size needed and take the same amount off both sides.

For example, if you decided to balance the borders on either side of the room as shown above, the calculations would be as shown below.

2630 (width of room) ÷ 300 (width of tile) = 8 full tiles + one part tile

300 x 8 = 2400 (coverage of full tiles)

2630 - 2400 = 230 (width of part tile)

230 ÷ 2 = 115 (width of border tiles on both sides)

So there will now be 7 full tiles and 2 balanced border tiles (each cut to 115 mm).

### Learning activity

Audio 6 (mp3 |6|KB)We've worked out the finished size of the border tiles on two sides of the room, but what about the two ends?

What will the finished size of the border tiles be at the two ends of the room if we decide to balance them as well?

How many field tiles will there be in between?

Do the calculations and check your answers with your trainer or other learners in your group.
